When using recent versions of the Projucer and clicking “Add existing files”, I cannot add any files, all are greyed out:
I did a git bisect, this is the first bad commit:
I tested on Ubuntu 18.04 and Debian 11, both times using the i3 window manager desktop.
In the meantime, I’ve learned to edit the .jucer file by hand 
Thanks for reporting, this should be fixed here:
I can confirm it works now!
Thanks for the quick fix!
But it seems now that select multiple directories is broken again. 
I’ll investigate more.
On my Ubuntu 21.04 install, multiple selection is working as long as canSelectDirectories and canSelectMultipleItems are passed, and canSelectFiles is not. In testing, it looked like zenity did not allow selecting both files and directories at the same time, so if both canSelectFiles and canSelectDirectories are passed, we show a file selection dialog.
On my Ubuntu 20.04.3 LTS it seems not working. 
I’ll make further test to see what’s hap.
OOPS, sorry for consuming your time for nothing, it’s all my fault. 
I badly tested it.
It is OK there too.
No worries, thanks for the update
